The 32-year-old New Zealander has penned a contract until the end of the season at Twickenham Stoop.

Quins director of rugby Conor O'Shea told the club's official website: "Given our injury situation and the time of the season, we are very fortunate to sign a player of Tim's experience. We are looking forward to welcoming him to the Harlequins family."

Molenaar spent nearly four years at Gloucester following a move from Nottingham in 2009.
